Vedclass · Answer

(B) Let us analyze each option:$A$: $Al^{3+}, Mg^{2+}, Na^{+}, F^{-}$ are isoelectronic species with $10$ electrons. For isoelectronic species,ionic size increases as the nuclear charge $(Z)$ decreases. The order $Al^{3+} (Z=13) $B$: The first ionization potential $(IP)$ generally increases across a period. However,$N$ has a stable half-filled $p$-orbital $(2p^3)$,so its $IP$ is higher than $O$. The correct order is $B $C$: Electron affinity $(EA)$ generally increases across a period,but $Cl$ has a higher $EA$ than $F$ due to the small size and inter-electronic repulsion in $F$. The order $I $D$: Metallic character increases down a group as ionization energy decreases. The order $Li < Na < K < Rb$ is correct.
